トクツシヨンの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat cushion for an automobile seat or the like, and in particular to an improvement in a seat cushion that allows a seated person to adjust the height and hardness of the front edge of the seat cushion as desired.

フイーリングを悪化させていた。 Conventional seat cushions have a front edge that is too high or too low for some people, too hard or too soft, and lacks thigh support. It was difficult to operate the pedals, and my thighs were prone to fatigue during long drives. Therefore, various types of seats have already been proposed in which the height and hardness of the front edge of the seat cushion can be adjusted according to the physique, preference, etc. of the occupant. However, this type of conventional seat changes the degree of inclination of the entire seat cushion, and as a result changes the height of the front edge of the seat cushion from the floor, which has the disadvantage that the entire seating posture changes. Therefore, it has been impossible to adjust only the feeling of pressure around the thighs, that is, the comfort of sitting, in a preferred sitting position. For this reason, the present applicant has supported an eccentric drum with a circular cross section on the seat cushion frame inside the front edge of the seat cushion, and by rotating this, the pressure feeling from the seat cushion on the thigh can be adjusted. proposed a mechanism to
(No. 54-140909) However, in this device, the eccentric drum is in direct contact with the pad material, and the contact area is large, so a large force is required to rotate the eccentric drum, making it difficult for the occupants to sit. In this case, the eccentric drum directly pushes up the pad material at the front edge, making the seat shape discontinuous and worsening the feeling in the thighs.
本考案は上記の欠点に鑑みて提案されたもの
で、その目的はシートクツシヨン前縁部の高さと
硬さが着座者が小さい力で、任意に調整できるよ

である。 In the present invention, a plate is disposed on the upper surface of a cavity provided in the width direction of the front edge of the seat cushion, and one end of the connecting rod is rotatably supported on the lower surface of this plate to connect the connecting rod. The other end of the rod is connected to a crank mechanism, and the rotation of the crank mechanism causes the connecting rod to move up and down, thereby making it possible to vary the height and hardness of the front edge of the seat cushion, or to use the aforementioned plate. It is divided into left and right halves so that the height and hardness of the front edge can be adjusted independently for the left and right sides.

Reference numeral 1 indicates a seat cushion, and 2 indicates a seat bag. The seat cushion 1 is composed of a pad material 3 and an outer skin 4. Further, as detailed in FIGS. 2 to 4, the front edge 5 of the seat cushion 1 has a cavity 6.
is perforated across the width direction of the front edge portion 5.
A plate 7 is disposed on the upper surface of the cavity 6 so as to be applied to the pad material 3 across the width direction of the front edge 5. This plate 7 has a slight curvature in the front-rear direction of the seat.

れている。 Further, a shaft 9 is rotatably supported by a knob 10 on the front side of the seat cushion frame, and a crank mechanism 11 is provided at the tip of the shaft 9. The crank mechanism 11 includes a crank arm 12 and a crank pin 13, and one end of a connecting rod 14 is rotatably supported at the tip of the crank pin 13. Furthermore, connecting rod 1
The other end of the plate 4 has a spherical shape and is rotatably supported on a pivot portion 15 fixed to the lower surface of the plate 7.

の硬さをも変えることになる。 Since the present invention is constructed as described above, as shown in FIGS. 2 and 3, when the knob 10 is turned to rotate the shaft 9 from the state shown in FIG.
A crank mechanism 11, ie, a crank worm 12, provided at the tip of the shaft 9 performs circular motion. This circular motion is transmitted via the crank pin 13 to the connecting rod 14.
is converted into reciprocating motion and transmitted to the connecting rod 14.
moves upward. As a result, the connecting rod 14 pushes up the plate 7 via the pivot 15, changing the height of the front edge 5 of the seat cushion, as shown in FIG. Also, since the pad material 3 is compressed by the plate 7 at the same time as the height is changed, the front edge 5
This will also change the hardness of the

Also, since the rotation of the shaft 9 is lifted by the pivot portion 15 provided on the plate 7 via the crank mechanism 11,
Unlike the conventional structure in which the rotating drum and the pad material are in direct contact, this seat cushion has the effect that the height and hardness of the front edge 5 of the seat cushion 1 can be adjusted with a small force while the occupant is seated. are doing.

This eliminates the feeling of a foreign body in the seated person and improves the feeling in the thighs. Further, the pad material is not damaged at the end of the plate 7.

きる。 FIG. 5 shows a second embodiment of the invention. Here, the plate 7 is divided into two parts 7a and 7b on the left and right sides of the front edge 5. In this case, the height and hardness of the front edge 5 of the seat cushion can be adjusted independently on the left and right sides, so that it not only has the same effect as the first embodiment, but also can be adjusted according to the various preferences of the seated person. It is possible to obtain the height and stiffness of the leading edge.

いうまでもない。 The structure of the pivot portion 15 of the plate 7 shown in the first and second embodiments is not particularly limited to this, and the recess may be provided directly on the plate. Needless to say, any structure is fine as long as it does not hinder the communication.

なるという効果を奏する。 As described above, according to the present invention, it is possible to freely change the height and hardness of the front edge of the seat cushion, so it can withstand long-term driving, reduces fatigue, and requires very little force. This has the effect of making adjustments possible.
